Principle Investigator

Timothy Sweeny

Tim Sweeny, PhD

I am an Associate Professor in DU's Department of Psychology. I received my PhD from Northwestern University in 2010. I then spent three years as a postdoctoral fellow at the University of California, Berkeley, before starting the VPEC Lab in Denver in 2013. I teach Perception, Introduction to Cog Neuro, a graduate Proseminar on Emotion, and a Matlab-based course on experimental design and computer programming. I have been an Associate Editor at Emotion since 2018, and I am the head of our department's Developmental Cognitive Neuroscience program.

Frontier Hall, Room 343, (303)-871-2191,

** Interested in joining the crew? I will be considering graduate applications this Fall, both for the ASC and Clinical programs. Please email me for more information.

She studies perception of nonverbal cues, including ensemble coding of facial expressions in typically-developing adults and perception of gaze direction in children with autism spectrum disorder. When not in the lab, Diana hangs out with her dog, Nietzsche, and jumps out of planes.
